Online sewage filtering system

Abstract

The invention discloses an online sewage filtering system which comprises a sewage sedimentation tank and a shell, and a cover plate, a water inlet pipe and a water outlet pipe are arranged on the sewage sedimentation tank; the shell is obliquely arranged on the sewage sedimentation tank, and the higher end of the shell penetrates through a tank body of the sewage sedimentation tank and the cover plate, is externally arranged and is provided with a driving unit; a spiral cleaning unit is arranged in an inner cavity of the shell, a filter screen is connected to the lower end of the shell, one end of the filter screen extends into the center of the bottom of the sewage sedimentation tank, and the filter screen is of a cylindrical structure with an opening in the top and wraps the outer side of the spiral cleaning unit; the spiral cleaning unit comprises a transmission shaft and a paddle, one end of the transmission shaft penetrates through the shell and then is connected to the driving unit, the paddle is of a spiral structure arranged in the axial direction of the transmission shaft, and the tail end of the paddle is attached to the cylindrical filter screen; the driving unit comprises a speed reducer and a motor; and an impurity discharging pipeline is also arranged on the shell. According to the invention, online sewage filtering is realized, the link of shutdown cleaning is reduced, and the filtering efficiency can be improved.

Description

technical field [0001] The invention relates to the field of garbage incineration sewage treatment, in particular to an online sewage filtration system. Background technique [0002] Sewage treatment methods include physical precipitation method, chemical precipitation method, biodegradation method, etc., but no matter which method is used for sewage treatment, in the process of sewage treatment, a large amount of sewage will accumulate at the bottom of the sewage filtration system after a period of operation sludge, and in order to ensure normal and effective sewage treatment, staff often need to clean up the residue and sludge inside the sewage filtration system. [0003] At present, the filtration system used in the sewage treatment of waste incineration power generation still needs to manually clean up the residue and sludge after shutdown. For example, the patent document with the application number CN201420244175. The water pipe stops flowing in and out, and the lower...

AI Technical Summary

Problems solved by technology

[0004] The present invention solves the filtration system used in the sewage treatment of waste incineration power generation, and often needs to manually clean up the residue and sludge after shutting down, which takes a long time, brings a large additional workload to the staff, and has certain potential safety hazards In order to solve the problem, a kind of sewage on-line filtration system is proposed, which realizes the online cleaning of residue and sludge through the spiral cleaning unit, which replaces the manual cleaning operation, and does not need to shut down the operation, and does not affect the normal operation of sewage filtration, thereby improving device availability
